Hi Alex, it's Patricia! I have Cormac here, who is loud and obnoxious but will very likely not notice Kathryn, given that they're in different houses and years, and Hamish, who is a sixth year Ravenclaw; besides knowing him from classes, he has a twin brother (Cassius Warrington) in her house and year, which probably be another point of connection. He can be rather shy when it comes to interacting with girls, but given that Kathryn is the quiet sort he'll probably be less awkward around her (it's the loud ones that make him panic).
